Datasheet
Product Features
The Intel® Xeon™ processor with 800 MHz system bus is designed for high-performance 
dual-processor workstation and server applications. Based on the Intel® NetBurst™ micro- 
architecture and the Hyper-Threading Technology, it is binary compatible with previous Intel 
Architecture (IA-32) processors. The Intel Xeon processor with 800 MHz system bus is scalable 
to two processors in a multiprocessor system providing exceptional performance for applications 
running on advanced operating systems such as Windows XP*, Windows Server* 2003, Linux*, 
and UNIX*.
